摘　　要：交流伺服电机被广泛应用于机械控制系统。传统方法在交流伺服电机的抗干扰补偿控制中受到外部因素的干扰较多,导致抗干扰补偿控制效果不好,使得电机转速波动较大,达不到理想效果。因此,基于差分进化算法提出了一种交流伺服电机抗干扰补偿控制方法。建立交流伺服电机控制模型,确定交流伺服电机抗干扰补偿状态,运用差分进化法对交流伺服电机抗干扰补偿的自适应控制速率进行调整,实现交流伺服电机的抗干扰补偿控制。经实验证明,使用所提出方法对交流伺服电机进行控制,电机的转速能够保持在1600~1700 r/min,最大控制速率为75.94 mm/s,转速较高且较为稳定,控制速率较高,能够及时对电机进行抗干扰补偿控制,具有较好的控制效果。AC servo motors are widely used in mechanical control systems.Traditional methods in the antiinterference compensation control of AC servo motors are often affected by external factors,resulting in poor antiinterference compensation control effect and large fluctuations in motor speed,which cannot achieve the desired effect.Therefore,a anti-interference compensation control method for AC servo motors based on differential evolution algorithm is proposed.Establish an AC servo motor control model,determine the anti-interference compensation state of the AC servo motor,and use differential evolution method to adjust the adaptive control rate of the anti-interference compensation of the AC servo motor to achieve anti-interference compensation control of the AC servo motor.Through experiments,it has been proven that using the method proposed in this article to control AC servo motors,the motor speed can be maintained at 1600~1700 r/min,with a maximum control rate of 75.94 mm/s.The speed is high and relatively stable,and the control rate is high.It can timely perform anti-interference compensation control on the motor,and has good control effects.
